Express in numbers six and three hundredths
Answer:
6.03
Step-by-step explanation:
'6' would be a whole number. When stating decimals, you would say the whole numbers before 'and'.
For example: 5.6 would be 'five and six tenths'. Note that five is before 'and'.
'Three hundredths' would be .03.
Therefore:
"Six and three hundredths" would be '6.03'.
Which of the following discrete random variables could be represented by a
probability histogram whose bars are all the same height?
O A. The number of goals scored per game by a soccer team in one
season
B. The ages of students in a high school
O C. The outcomes of spinning a spinner with five equal sections
O D. The outcomes of rolling a weighted die
Answer: The outcome of spinning a spinner with five equal outcomes
Step-by-step explanation:
The discrete random variable that could be represented by a probability histogram whose bars are all the same height is;
Option C; The outcomes of spinning a spinner with five equal sections
The probability histogram is a type of histogram whereby the height of each bar shows the true probability of each outcome of a specific number of trials.
Now, let us look at the options;
Option A; This cannot be represented by a probability histogram because it doesn't show probability.
Option B; This cannot be represented by a probability histogram because it shows just ages and doesn't show probability.
Option C; This can be be represented by a probability histogram because it shows the probability of each outcome of spinning five equal sections.
Option D; This cannot be represented by a probability histogram because it should show the probability of each outcome and not just that of one weighted die.

WHAT IS THE PYTHOGERON TRIPLETS IF ONE NUMBER IS 36
Answer:
Step-by-step
Let the given number be n>2.
For n even, n2+((n/2)2–1)2=((n/2)2+1)2.
For n odd, n2+((n2–1)/2)2=((n2+1)/2)2
use the forumla to find u r answer
standard form of a pythagorean triplet is 2m, m²+1, m²-1
let us take 2m as 36. so
2m=36, m=36/2
therefore m=18
m²+1 =18²+1 = 324+1 =325
m²-1 =18²-1 = 324-1 =323
therefore 36,325,323 form a pythagorean triplet.
For checking, 36²+323² should be equal to 325²

There are several vendors at the carnival who sell products and also advertise their businesses.
Steve works for a recreational company that sells ATVs, dirt bikes, snowmobiles, and motorcycles.
His boss paid him $500 for working all of the days at the carnival plus 5% commission on all of the sales made at the carnival.
What was the minimum amount of sales Steve needed to sell if he earned more than $1,500?
Answer:
Step-by-step explanation:
third side is <11+9 or <20cm
or >11-9 or >2
so third side=15 cm
Let x be the sale.
Then 500+.05x>1500
.05x>1500-500
.05 x>1000
x>$2000
minimum sale=$2000
Answer:
Length of Third Side = 15 cm,

A new car is purchased for 15700 dollars. The value of the car depreciates at 7.5% per year. To the nearest year, how long will it be until the value of the car is 10100 dollars?
Answer:
10100=15700(1-0.075)^x
10100=15700(0.925)^x
divide both sides by 15700
0.925^x=101/157
convert decimal
(37/40)^x=101/157
take the log
x= log 37/40 (101/157)
x= 5.65824
It will take almost 6 years to depreciate the value of the car to 10100 dollars.

5. A silo was constructed at a farm in the shape of a right circular cylinder. It was built with an
approximate volume of 842,411 cubic meters and a height of 85 meters. What was the length of the diameter
of the base, to the nearest meter?
Answer: 112 meters
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder (V) : π x radius ² x heightReplacing with the values given :
842,411 = π x r ² x 85
Solving for r:
842,411 / (π x 85) = r²
3,154.67 = r²
√3,154.67 = r
56.16 m = r
Finally, we have to multiply the radius by 2 to obtain the diameter:
56.16 x 2 = 112 meters

a. Write an equation for the line in point-slope form.
b. Rewrite the equation in slope-intercept form.
Answer:
1.y−7=3(x+3)
2.y=3x+16
Step-by-step explanation:
use point-slope formula to find the slope and plug it into the equation
y-y₁=m(x-x₁)
slope= -[tex]\frac{y2-y1}{x2-x1}[/tex]
plug in the value of x and y from both of the coordinates into this equation and then use one set of points and slope to get your equation

A balloon rises vertically at the rate
of 10 ft. per second. If it encounters
a wind that gives a horizontal displace-
ment of 5 feet per second,
find (to the nearest whole degree)
the angle with the horizontal at
which the balloon rises.
a.
b.
find (to the nearest 10 feet) its
distance from the starting point
after one minute.
Answer:
a) 63°
b) 600ft
Step-by-step explanation:
To solve the above question, we would be using Trigonometric function
a) Find (to the nearest whole degree)
the angle with the horizontal at
which the balloon rises.
This above question a is a right angled triangle that is solved for using Trigonometric function of tan
From the question, we told that,
Vertical distance ( opposite side) = 10 feet
Horizontal distance ( adjacent side) = 5 feet.
Tan θ = opposite side/ adjacent side
Tan θ = 10/5
Tan θ = 2
θ = arc tan (2) or tan -¹(2)
θ = 63.434948823°
θ = 63°
The angle with the horizontal at
which the balloon rises to the nearest whole degree is 63°
b) find (to the nearest 10 feet) its
distance from the starting point
after one minute.
Distance = Speed × time
Time is given in the question as 1 minute
We would convert it to seconds = 60 seconds
We are told in the question that the balloon rises vertically at the speed of 10ft/s
Distance = 10ft/s × 60seconds
Distance from the starting point per minute = 600ft

Samantha and Luis are attempting to determine the average number of library books that seventh-grade students check out at one time. Samantha surveys every other seventh grade student leaving the library. She samples a total of 40 of the 200 seventh graders. Luis samples 30 of the 200 seventh grade students at random in the school cafeteria. Whose sample is the most random? Luis because his sample is taken from the population of all seventh graders Luis because he samples fewer students Samantha because she samples more students Samantha because her sample is taken from the population of students who use the library
Answer:
Luis, because his sample is taken from the population of all seventh graders. However, Samanthan has the advantage of having a bigger sample, and that makes it more representative.
Taking the sample of the library as Samantha did, is biased, because most of the students there is checking a book, and the aim of the study is not only the ones that use the library, but in general the seventh grade students.

A pie chart titled Percentages in salad mix. 40 percent is iceberg, 27 percent is romaine, 15 percent is spinach, 12 percent is arugula, 6 percent is carrots. Dominic buys a 64-ounce container of salad mix. About how many ounces of romaine lettuce does the container have? 6 ounces 12 ounces 18 ounces 27 ounces
Hi! here's your answer!ヾ(￣▽￣)
Step-by-step explanation:
Your answer is 18 ounces of romaine lettuce!
Have a nice day/night~ (｡･∀･)ﾉﾞ
The correct option is 18 ounces. The weight of romaine lettuce in salad mix container is 17.28 ounces.
Given to us:
iceberg = 40%
romaine = 27%
spinach = 15%
arugula = 12%
carrots = 6%
The total weight of salad mix container = 64 ounces
Romaine lettuce the container have is 27% of the total weight of salad mix container Dominic buys. Therefore,
weight of romaine lettuce in salad mix container,
= 27% of the total weight of salad mix container
= 27% of 64 ounces
= [tex]\dfrac{27\times 64}{100}[/tex]
=17.28 ounces
Hence, the weight of romaine lettuce in salad mix container is 17.28 ounces.
